domain name system

Security threats are persistent and growing. While many organizations have adopted a defense-in-depth strategy — utilizing anti-virus protection, firewalls, intruder prevention systems, sandboxing, and secure web gateways — most IT departments still fail to explicitly protect the Domain Name System (DNS). But this Internet protocol doesn’t have to be a vulnerability.

With the constant drumbeat of news reports about security breaches, cyber security is hard to ignore. Organizations understand that they need comprehensive security solutions, yet significant gaps remain. Malicious actors have evolved their methods to leverage the vulnerabilities of the Domain Name System (DNS), and attacks that utilize this vector are increasing in number.

Cybercriminals are evolving. Increasingly, they are capitalizing on the open and unprotected nature of the Domain Name System (DNS) to launch damaging phishing, malware, and ransomware attacks. How are you proactively protecting your network and users from these targeted threats? Here are five things to ask yourself as you consider a DNS security solution for your company.

The cyber threat landscape is dynamic and accelerating. The Domain Name System (DNS) is a vulnerability in many organizations’ defenses that malicious actors are increasingly exploiting. The following DNS best practices, when coupled with an enterprise threat protection service, will aid you in identifying, blocking, and mitigating targeted threats such as malware, phishing, ransomware, and data exfiltration.

"High-profile cyber attacks seem to occur almost daily in recent years. Clearly security threats are persistent and growing. While many organizations have adopted a defense-in-depth strategy — utilizing anti-virus protection, firewalls, intruder prevention systems, sandboxing, and secure web gateways — most IT departments still fail to explicitly protect the Domain Name System (DNS). This oversight leaves a massive gap in network defenses.
But this infrastructure doesn’t have to be a vulnerability. Solutions that protect recursive DNS (rDNS) can serve as a simple and effective security control point for end users and devices on your network.

DNS is a well-worn data exfiltration and communication vector. Explore why targeted threats continue to use the DNS protocol to exfiltrate sensitive information, how it’s done, and what might be next in the evolution of this attack vector.

Examine the business impact of malware, ransomware, and phishing, as well as the cost of the average data breach. Given the significant economic impact of these threats, understanding your financial exposure and employing a layered defense simply makes sense.

Every user’s first interaction with your website begins with a series of DNS queries. The Domain Name System (DNS) is a distributed internet database that maps human-readable names to IP addresses, ensuring users reach the correct website when entering a URL. DNS mappings are maintained in special-purpose servers called DNS nameservers. When a user enters your company’s URL, a DNS query is routed to a DNS nameserver containing the address mappings for your company’s internet domain.

The Domain Name System (DNS) is a hierarchical system that provides the IP addresses that correspond to a given Fully Qualified Domain Name (FQDN, often called a hostname or domain name). At the top of the tree structure are thirteen “root” Domain Name Servers that have the primary and secondary IP addresses of the DNS Authorities for all domains on the Internet.
